What tension must a 50.0 cm length of string support in order to whirl an attached 1,000g stone in a circular?

Question

path at 5.00m/s?

Answer 1

Anything moving in a circular path experiences centripetal force

F = mv^2/r

here m = 1.0 kg, v = 5 m/s and r = 0.5 m

The centripetal force on the stone is hence 1*(5^2)/0.5 = 50 N

This is the tension that the string must support
